Abstract
Systems and methods for treating a plurality of tissue sites include a multi-port therapy unit. The multi-port therapy unit includes a plurality of patient-side ports each fluidly coupled to a plurality of conduits and a fluid reservoir fluidly coupled to the plurality of ports. A plurality of pressure sensors are associated with the plurality of patient-side ports to determining a pressure associated with each conduit. A controller is operatively coupled to the plurality of pressure sensors to receive treatment pressure data, monitor pressure for each pressure sensor of the plurality of pressure sensors, and signal an alarm condition if the pressure is outside of a pre-selected range. The system includes a reduced-pressure source fluidly coupled to a dressing at each tissue site through the multi-port therapy unit.
